Mini-Tubular Heaters
With the capability to be formed into many shapes, the Mini-Tubular is adaptable to a variety of applications. Swaged or drawn Alloy cable, compacted magnesium oxide and a helical or straight resistance element are the assembled components of the Mini-Tubular. Small diameters and cross-sections allow a quick response, providing heat in tight spaces where most heaters cannot be installed. The typically spiral design allows heat to be applied to the full circumference of the part. The small diameter Mini-Tubular Band Heaters at 3/4″ and 7/8″ inside diameter are exact OEM replacements. Many are available from stock. Also available is a square profile design that increases surface contact for improved conductive heat transfer. An internal thermocouple in some sizes allows for precise temperature monitoring and control. Mini-Tubular Heaters can also be supplied straight for field bending.
